Please correct me here teck guys, but the 3.2 is tuned to use Super Unleaded as its 99 Ron.

If you suddenly add Normal Unleaded Detination may occure (this normally happens with Import Turbo cars but not sure if it will happen on a 3.2 )

Anyway difference in power id say approx 8 BHP
But have never put normal Unleaded in the tank to try.

Does anyone know if its possible to Re Set the ECU ?

You can reset the adaption values using VAGCOM, or just disconnect the battery for 10 minutes, the ECU will not allow detonation and will instantly back off the timing and hence you'll get less power if you go from super to standard 95.

I bet the difference is less than we think. Despite the 98ron suggestion for the 3.2 it seems unlikely that audi didn't engineer it to run merrily on cheaper petrol for the far corners of europe and I'd guess that the manufacturers power figures can be produced on 95.

I prefer to run BP ultimate in the 3.2. I really noticed a difference in low rev torque over optimax. I was suitable amazed (after religiously running Optimax in my last two motors). So now I run BP ultimate when available or default to optimax. Shells garages are in abundance in Chester, not so with BP.

Recent Evo mag summed it up nicely, go with what ever your car feels best on, and throw in a few tanks of optimax for engine cleaning purposes.
